React Formik:如何在不手动处理状态的情况下使用自定义onChange？

import { Formik, Field } from 'formik';

const MyForm = () => {
  const handleCustomChange = (event, setFieldValue) => {
    // 在这里处理自定义的onChange逻辑
    const newValue = event.target.value.toUpperCase();
    setFieldValue('myField', newValue);
  };

  return (
    <Formik
      initialValues={{ myField: '' }}
      onSubmit={values => {
        console.log(values);
      }}
    >
      <form>
        <Field
          name="myField"
          render={({ field, form }) => (
            <input
              type="text"
              {...field}
              onChange={event => handleCustomChange(event, form.setFieldValue)}
            />
          )}
        />
        <button type="submit">提交</button>
      </form>
    </Formik>
  );
};

export default MyForm;
